The European e-commerce landscape is reaching a historic turning point. On March 26, the first edition of EO2S (Ecommerce Open Source Summit) was held at Issy-les-Moulineaux. Organized by the Friends of Presta association, this event was far more than a simple trade show; it was a manifesto for a Europe reclaiming its digital sovereignty.
For Esokia, this day marked a major milestone. Our Director, Michel Demari, engaged in meaningful discussions with the visionaries of this new alliance: Mikołaj Król, the CEO of both PrestaShop and Sylius and Olivier Binet, the Managing Director of PrestaShop. This meeting highlights Esokia’s growing influence at the center of market transformations.
A Strategic Convergence: Sylius × PrestaShop
The summit signaled a definitive shift: the convergence of PrestaShop and Sylius. For merchants and agencies like Esokia, this isn't just a technical update—it’s a shared vision built around the Symfony framework.
With the launch of PrestaShop 9 and Sylius 2.0, module interoperability and shared governance are becoming a reality. This common foundation offers unprecedented flexibility, combining PrestaShop’s robust business logic with Sylius’s "best-of-breed" modularity.
The core themes addressed during the conference included:
Digital Sovereignty: Taking back control from Big Tech (GAFAM)
Faced with dependency on GAFAM and new European regulations (DMA/DSA), choosing a sovereign cloud has become a priority. Open Source is the definitive answer, ensuring code transparency and total control over customer data while guaranteeing compliance with GDPR and NIS2.
Generative AI: A 22% Boost in Average Order Value
AI is reshaping e-commerce through agentic commerce and GEO (Generative Engine Optimization). Partners reported a 22% increase in average basket value following the implementation of AI-driven cross-selling on PrestaShop and Magento platforms.
Technical Performance: Every Second Counts
Site architecture is a direct driver of ROI. Agility is now achieved through Headless & Composable Commerce. Core Web Vitals remain critical: an LCP (Largest Contentful Paint) exceeding 2.5 seconds can result in a 5% to 10% drop in conversion rates.
The PrestaShop × Sylius Ecosystem
The alignment of these two communities ensures the longevity of PHP in the e-commerce sector. This interoperability allows for the creation of hybrid, ultra-high-performance architectures.
Open Source: A Proven, Robust Model
The success stories presented at EO2S confirm the maturity of open source solutions in the enterprise space. Key takeaways included:
Successful migrations from proprietary SaaS solutions.
Scaling businesses to multi-million euro turnovers.
International deployment across diverse European markets.
These case studies prove that open source is no longer just an alternative, but a sustainable strategic solution.
Towards A More Responsible and Accessible E-commerce
The 2026 edition also highlighted Green IT and digital accessibility. With the enforcement of regulations such as the European Accessibility Act, merchants must integrate these requirements from the design phase.
The benefits are clear:
Reduced carbon footprint.
Enhanced user experience (UX).
Full legal compliance.
Again, the open-source model provides the flexibility needed to adapt platforms deeply to meet these challenges.
Security and Compliance: Pillars of Digital Trust
In an era of rising cyber threats, security is a non-negotiable success factor. Discussions focused on GDPR, NIS2, PCI DSS, and fraud prevention. Open source stands out here through:
Code transparency.
Collaborative security efforts.
An active global community of contributors.
For companies, this means better risk management and increased user trust.
Community and Economic Models: The Keys to Sustainability
Finally, EO2S 2026 emphasized that the longevity of open source relies on a balance between community contribution and a viable economic model. Initiatives like Friends of Presta illustrate the desire to structure the ecosystem, giving a voice to both agencies and individual contributors. Without a sustainable economic model, no community can thrive—a challenge fully embraced by all stakeholders, including Esokia.
